Question
The average speed of a bus is 2/3 of the average speed
of a car which covers 1800 km in 20 hrs. What is the average speed of the bus?Solution
Distance covered by car= 1800 km, Time = 20 hrs. Speed of a car= (Distance )/Time = (1800 )/20 = 90 km/hr. Average speed of a bus = (2 )/3 × 90 = 60 km/hr.
